It is not a requirement to show RADAR readings in Illinois.
Any object large enough to produce an echo. Hills and mountains for instance
Radar displays show where precipitation is they also show the winds within thunderstorms which help them see rotation in a thunderstorm to pick out where a tornado is possibly forming.
Nope. The radar is only a confirmation of the officer's visual estimation.
The radar shows the position and the distance of an object.
speed of movement of the objects detected.
All they have to prove is that it was within manufacturer's specifications and calibrated properly, so when stopped by police, they don't need to show you the radar gun, when you ask to see it. An officer does not, and more than likely, will not show you what speed you were going on there radar. That issue would come up in court.
Walter Eugene "Radar" O'Reilly was on the show for the first 7 seasons. [out of 11 seasons].
Ground penetrating radar can detect things underground and show where excavation would be useful.
No the law even says they do not have to show you the gun what so ever.
Your question has nothing to do with FIREARMS.
No they do not. There is no state where it is a legal requirement.
Doppler radar is commonly used to detect precipitation and how much is coming down and can also be used to measure wind speed.
They have to show that it is has been tested and is functioning properly.
The applications of a radar is,Whale's radar,ship's radar,submarine's radar,plane's radar.
Radar charts show moisture (both liquid and frozen). Radar charts are very useful in both summer and winter months (actually year-round) because of the ability to discern liquid and frozen moisture. Radar Summary charts only show liquid moisture (no ability to see ice, snow or mixed precipitation) but show thunderstorm cell movement (directional arrow vectors and speed in knots) as well as individual cell height in thousands of feet (400 = 40,000 feet). Also watch and warning boxes are added to depict areas of strong or severe weather not shown on Radar charts.
Walter he was a famous character
Weather radar devices electronically convert the reflected radio waves into picture that show the location and intensity of precipitation and the speed of the wind.
The Doppler radar help scientists by the color code which is on the screen, and the colors show if the tornato if it is F0-F1-F2-F3-F4-F5. F5 is the strogest, most incredible tornato out of the six.
